Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

You need something like tmpgenc to make Blu-ray compliant discs

I don't really understand this though, the cost per GB of a blank double layer bluray is higher than an hard drive. Just store Blu-ray images (or direct rips) on the disc and access them on your device. In this way you don't need to worry about disc damages, bad burns, lost media, and so on.

At the price of a disc + the time to source and take a full disc rip + the time to source a good scan of the cover and disc surface + printing labels and covers + the bluray box (you said you want to look professional so you aren't planning to just keep them in a spindle and use a sharpie, right?) You're basically paying almost the same of a real disc

Why?

If you already have the ripped copies, they're easier and more convenient to browse and watch, you're basically just filling up your shelves with worthless coasters.

Yeah.. I wanted to get 4k collection of lotr and hp, but it's too much expensive. Then I downloaded the iso's and wanted to burn them.. And it would be much cheaper to just buy the whole damn collection, so I just browse it digitally.

Purchase a company such as Sony.

Is bd the type of Disc?

Fastest way? Burn it as a data disc. You can also use software to create a menu but it's not something you can do with FOSS, you will probably need to pay a lot for the software

There are many user-friendly Blu-ray burning programs available that can guide you burn blu ray disc. Just make sure you have a compatible Blu-ray burner and blank discs before you start.
